Question about ASUS ROG Strix Z490-G Gaming (Wi-Fi)

I have DDR4-3200 Rams in it. But when I activate the XMP mode in the bios and it then enables the full bandwidth, the computer no longer starts. Can anyone help me? My Rams are: Corsair Vengeance LPX, 2x, 8GB, DDR4-3200, DIMM 288. CPU: Intel i7-10700K With my last mainboard from Asus, it ran flawlessly at 3200MHz.
